DAC 4-CH R-2R 12-bit 24-Pin PDIP N

The MAX526/MAX527 contain four 12-bit, voltage-output digital-to-analog converters (DACs). Precision output buffer amplifiers are included on-chip to provide voltage outputs. The MAX527 operates with ±5V power supplies, while the MAX526 utilizes -5V and +12V to +15V supplies. Offset, gain, and linearity are factory calibrated to provide the MAX526’s 1LSB total unadjusted error (TUE). These devices feature double-buffered interface logic with a 12-bit input register and a 12-bit DAC register. Data in the DAC register sets the DAC output voltage. The MAX526/MAX527 have an 8-bit-wide data bus. Data is loaded into the input register using the two write operations with an 8-bit LSB write load and a 4-bit MSB write load. An asynchronous load DAC (active-low LDAC) input transfers data from the input register to the DAC register. All logic inputs are TTL and CMOS compatible. The MAX526/MAX527 are available in 24-pin, 300 mil plastic DIP, Ceramic SB, and wide SO packages.
